davidvasta Thank you for this info. We will surely consider upgrading to 2019.

 

About calling support...  I have been in contact with Microsoft Premium Support about this issue since late May and no one has ever mentioned this as a probable cause of our mail flow problem.

 

update:

 

Microsoft has informed us that your ticket has been escalated to the Product Group (PG) team for further investigation and resolution. The PG team consists of specialized professionals responsible for developing and maintaining Microsoft products, providing advanced technical support for complex issues, bug fixes, expert advice, and custom solutions.
 
We understand the importance of a timely response and resolution to your issue. However, we would like to set the expectation that it may take some time to hear back from the PG team. This is due to several factors that can influence the response time:

  1. High Volume of Requests: The Microsoft PG team handles a significant number of requests from users worldwide, which can affect response times.
  2. Complexity of Issues: Many issues require thorough investigation, replication, and analysis. This process can be intricate and time-consuming, involving multiple stages of debugging and testing.
  3. Coordination Across Teams: Resolving certain issues may require coordination with various internal and external teams, adding to the time needed for a resolution.
  4. No ETA for Resolution: The PG team does not provide estimated times for resolution. Some issues may take weeks or even months to resolve.
  5. Resolution Not Guaranteed: While the PG team works diligently to address all escalated issues, a resolution is not always guaranteed.

What we Expect:

  1. In-Depth Investigation: The PG team will perform a detailed investigation, which may take additional time.
  2. Ongoing Updates: CSS team will keep you informed of the progress and any actions being taken by the PG team
  3. Frequent Requests for Fresh Logs: The PG team may request fresh logs several times. To help them find a resolution, it is important to cooperate and be patient
